Why is this now flagged ?

Perhaps the most important question which I have yet to see anyone pointing out. Those bit rate numbers are appalling! 2-4Mbps average bitrate? For a services you are paying for? I knew Netflix has gotten bad but this is worse than I thought. Even some high end YouTube Content does better than that. It should be 8Mbps minimum. And at this bitrate the difference between H.264 and AV1 wont be so obvious.

>Those bit rate numbers are appalling! 2-4Mbps average bitrate?

While those may sound low, what I'm thinking is Netflix didn't see any benefit in perceptual quality (or VMAF scores) but sending more bits down the pipe and increasing their bandwidth bill.

That is the problem. The think VMAF as the gospel, and AV1 is extremely well tuned for it.

VMAF is better than SSIM PSNR but it is still far from perfect. And it is a reason why most torrent are still using HEVC and AVC.
